Product Introduction
| Silica Brick | |
| Siliceous refractory material is a refractory material mainly composed of silica. Usually, the SiO2 content is not less than 93%. The main variety is silica brick. Using silica as raw material and firing at 1350-1430 ℃, the true density must be within 2.31-2.42g/cm3. | |
| Product characteristics: (1) Under long-term high temperature and load conditions, the volume is stable and the creep rate is low at high temperatures. (2) Good thermal shock resistance above 600℃, able to adapt to the variability of hot blast furnace temperature, and maintain the integrity of bricks and masonry. (3) Good resistance to chemical attack. | |
| Product application： The main use of coke oven silica bricks is to build the walls, ramps, combustion chambers, carbonization chambers, and furnace tops of the regenerative chamber of the coke oven. | |
